Question

What is the value of y?

Answer 1

I think the value of y is 40

Explanation:

Here,

2y+ y+ 10+50=180°( sum of all angles of triangle)

or, 3y+ 60=180

or, 3y=180-60

or, 3y=120

or, y= 120÷3

:.y= 40

Answer 2

C, 40 degrees

Explanation:

All the angles of a triangle add to 180 degrees according to the Triangle Sum Theorem.

Since all angles sum to 180, we can set all the values to add to 180.

We have:

`2y+y+10+50=180`

Combining like terms, we have:

`3y+60=180`

Subtracting 60 from both sides gets us

`3y=120`

Dividing by 3 from both sides equals

`y=40`
